Radioisotopic dating parent daughter

In other words, the decay of the parent radioisotopes was accelerated by different amounts, the decay of those yielding older "ages" (the alpha-decayers) having been accelerated more.Obviously, if radioisotope decay was accelerated, say during the Genesis Flood, then the radioisotope decay "clocks" could never be relied upon to "date" rocks as many millions of years old.

The radioisotope methods, long touted as irrefutably dating the earth's rocks as countless millions of years old, have repeatedly failed to provide reliable and meaningful absolute ages for Grand Canyon rock layers.Both laboratories use standard, best-practice procedures on state-of-the-art equipment.The model K-Ar ages for each of the samples ranged from 405.1±10 Ma to 2574.2±73 Ma.These are former sedimentary and volcanic strata that have been transformed by heat and pressure, possibly during the intense upheavals when the dry land was formed on Day 3 of Creation Week.Among these metamorphosed volcanic strata are amphibolites, belonging to the Brahma Schist.
